What are the key components of a computer network?
Devices: Devices are members of the network, such as computers, laptops, smartphones, printers, switches, routers, and servers. These devices are used for operation and communication in the network.
What are the main components of a computer network?
Communications media: Communications media are used to carry data within a network, such as cable, wireless radio or infrared, and optical fiber.
Protocol: Protocols dictate the organization and handling of data in networks. These protocols can exist across network layers, such as physical, data, network, transport, session, presentation, and application.
Basic security: A variety of security mechanisms are used to ensure the security of the network, such as firewalls, antivirus software, and encryption mechanisms.
Server: A server is a special type of computer that provides services to other devices on the network, such as data storage, web hosting, file sharing, and other services.
Switch and Router: Switch and router help in transmitting data in the text of data packets in the network and between different segments of the network.
Network Topology: Network topology determines the type of mutual connections between devices on a network. Some of the major network topology categories are star, bus, ring, mesh, and hybrid.
The main components of a Computer network are as follows :
IP Addressing: IP addresses are used to identify devices on a network. These addresses are critical to global network operation and are essential for Internet communications.
Network Data Communication Protocol (TCP/IP): TCP/IP are important protocols for network communications, guiding the sending, receiving, and handling of data.
Gateway: A gateway is a device that connects one network to another. This means that the gateway provides users of one network access to other networks.
DHCP Server: A DHCP (Dynamic Host Configuration Protocol) server supplies new network devices with the IP addresses, subnet masks, and gateways they need.
DNS Servers: DNS (Domain Name System) servers are used to map a domain name to its referential IP address, which is needed to get across the Internet.
Switching Mechanism: Switching mechanism is used to determine the path of data packets in the network. These are special devices that transmit data to underlying devices in the network.
